Description

Technical Field

[0001] This utility model belongs to the technical field of steel column-beam concrete structure building, and relates to a corner column joint structure of steel column-beam concrete structure building. Background Technology

[0002] In the current construction industry, steel structures, due to their high strength, are widely used in scenarios such as factory construction. Most steel structures are formed by welding, riveting, or bolting, connecting prefabricated steel sections. However, the mortise and tenon joint technique commonly used in traditional Chinese architecture, where the tenon and mortise fit together at the intersections, creates a unique flexible structure. This structure can withstand large loads and allows for elastic deformation, offsetting some seismic energy during earthquakes and reducing the displacement angle under seismic loads. This technique has also been applied to steel structure buildings.

[0003] For example, the patent application number CN202021282274.1 discloses a two-way hoop-type steel structure tenon and mortise connection structure. A square steel pipe secondary beam is inserted into a cross mortise. One end of the square steel pipe secondary beam has a secondary beam tenon groove, and the opening of the secondary beam tenon groove faces the main beam tenon groove. The cross mortise is used to insert into the cross mortise groove. A steel plate is provided outside the cross mortise groove, and the outer surface of the steel plate is flush with the outer surface of the square steel pipe column.

[0004] The above structure still has shortcomings: the main beam is prone to shifting along its length when placed on the column, making it difficult to align the sub-beams during the assembly process of fastening them to the ends of the main beam, resulting in laborious and inconvenient assembly. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a corner column joint structure for steel column-beam concrete structures. The technical problem this utility model aims to solve is that existing corner column joint structures are not convenient to assemble.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A corner column joint structure for a steel column-beam concrete structure includes a lower corner column, a main beam, and a secondary beam. The lower corner column is in the shape of a vertical tube, and its side wall has at least two circumferentially spaced lower rectangular notches. The main beam and the secondary beam are both horizontally arranged and perpendicular to each other. The upper side of the main beam and the lower side of the secondary beam have mutually interlocking clearance notches. The ends of the main beam and the secondary beam are respectively inserted into the two lower rectangular notches and interlocked through the clearance notches. The main beam and the secondary beam are rectangular steel pipe beams or C-shaped steel beams with their openings facing upwards. The lower side of the end of the main beam is integrally connected with a downwardly arranged main limiting buckle. The end of the main beam extends horizontally through the lower corner column, and the main limiting buckle is interlocked with the outer wall of the lower corner column.

[0008] The lower corner columns provide support for the ends of mutually perpendicular main beams and secondary beams at the corners of the building. The main beams and secondary beams can be inserted into two different lower rectangular notches to achieve width-direction positioning, ensuring their stable relative position with the lower corner columns. The clearance notches on the upper and lower sides of the main beams and secondary beams facilitate mortise and tenon joints, improving the connection stability by positioning the main beams and secondary beams together. By designing the main beams and secondary beams as rectangular steel pipe beams or open-ended C-beams, it is easier to fill the main beams, secondary beams, and lower corner columns with concrete, while ensuring sufficient strength of the main beams and secondary beams, thus enhancing their strength. To enhance structural strength and high-temperature resistance, an integrally connected main limiting buckle is installed on the lower side of the main beam end. The main beam end passes through the lower corner column, and the main limiting buckle engages with the outer wall of the lower corner column. During installation, the main beam can be inserted into the lower rectangular notch from above while the main limiting buckle engages with the outer wall of the lower corner column. Then, the secondary beam is installed from top to bottom. The main beam is positioned with the lower corner column along its length, which avoids axial backlash of the main beam causing the clearance notch to shift. This allows the secondary beam to smoothly and accurately engage with both the lower rectangular notch and the clearance notch of the main beam simultaneously for assembly, improving assembly convenience.

[0009] In the corner column joint structure of the aforementioned steel column-beam concrete structure, the lower rectangular notch has an upwardly protruding positioning protrusion at its lower edge, and the lower side of the main beam has a positioning hole, into which the positioning protrusion is inserted. Thus, after the main beam is placed within the lower rectangular notch, the positioning protrusion and the positioning hole further provide axial positioning for the main beam, preventing it from shifting back and forth along the axial direction, ensuring accurate installation, improving assembly convenience and fitting precision, and making the structure stable.

[0010] In the corner column joint structure of the aforementioned steel column-beam concrete structure, the two side walls at the ends of the main beam have vertically extending main overlapping pieces along the length of the main beam. A main limiting buckle is integrally connected to the lower edge of the main overlapping pieces. The upper edge of the side wall of the lower corner column has a vertically arranged strip-shaped downward cut, and the main overlapping pieces are inserted into the downward cut. This insertion of the main overlapping pieces into the downward cut further improves the fit accuracy between the main beam and the lower corner column. Simultaneously, during subsequent welding, a longer vertical weld can be formed, increasing the welding strength between the main beam and the lower corner column, making the structure more stable.

[0011] In the corner column joint structure of the aforementioned steel column-beam concrete structure, the lower side of the secondary beam is integrally connected with a downward-facing secondary limiting buckle. The secondary beam is supported on the lower corner column, and its end extends out of the lower corner column, allowing the secondary limiting buckle to engage with the outer wall of the lower corner column. This allows the secondary beam to be pre-positioned along its length with the lower corner column via the secondary limiting buckle during installation, ensuring a stable position for the secondary beam during subsequent welding and improving installation convenience.

[0012] In the corner column joint structure of the aforementioned steel column-beam concrete structure, the corner column joint structure also includes an upper corner column in the shape of a vertical tube. The lower edge of the side wall of the upper corner column has at least two upper rectangular notches. The upper corner column is supported on the upper end of the lower corner column, and the positions of the upper rectangular notches correspond to the positions of the lower rectangular notches. The main beam and the secondary beam are respectively engaged within the two upper rectangular notches. In this way, the upper corner column can provide constraint on the main beam and the secondary beam from above, keeping the positions of the main beam and the secondary beam stable. The upper rectangular notches can ensure sufficient welding area between the upper corner column and the main beam and the secondary beam, making the structure more stable.

[0013] In the corner column joint structure of the aforementioned steel column-beam concrete structure, the two side walls at the ends of the secondary beam have vertically extending secondary lap pieces along the length of the secondary beam. A secondary limiting buckle is integrally connected to the lower edge of the secondary lap piece. The main lap piece and the secondary lap piece are staggered vertically. The lower edge of the side wall of the upper corner column has a vertically arranged strip-shaped upper cut, and the secondary lap piece is inserted into the upper cut. This combination of the secondary lap piece and the upper cut provides a larger welding area while simultaneously positioning the secondary beam, ensuring a stable connection between the secondary beam and the upper corner column. Furthermore, the welding positions of the main beam and the secondary beam are distributed on the lower and upper corner columns respectively, resulting in a more uniform load distribution.

[0014] In the corner column joint structure of the aforementioned steel column-beam concrete structure, both the lower end of the upper cut joint and the upper end of the lower cut joint are flared. This facilitates the insertion of the main lap joint downwards into the lower cut joint and the secondary lap joint upwards into the upper cut joint, making the insertion process more convenient.

[0015] In the corner column joint structure of the aforementioned steel column-beam concrete structure, a vertically shaped support plate is located within the clearance notch on the main beam, and the support plate is supported between the two side walls of the secondary beam. When the clearance notch at the end of the secondary beam engages with the clearance notch at the end of the main beam, the support plate can be embedded between the two side walls of the secondary beam to provide internal support, increasing the structural strength of the secondary beam end and providing more precise positioning for the secondary beam, thus ensuring the overall structure is stable and reliable.

[0016] In the corner column joint structure of the aforementioned steel column-beam concrete structure, the intersection of the main beam end and the secondary beam end has a vertically penetrating grout passage. This allows concrete to flow smoothly through the grout passage into the lower corner column during pouring, ensuring the quality of the concrete filling.

[0017] In the corner column joint structure of the aforementioned steel column-beam concrete structure, several spaced reinforcing plates are welded and fixed between the two side walls of the C-shaped main beam and secondary beam. This helps to improve the structural strength of the main beam and secondary beam, ensures the stability of their internal structure, and guarantees the concrete pouring effect.

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] During installation, the corner column joint structure of the steel column-beam concrete structure can be installed by first inserting the main beam into the lower rectangular notch from above, while simultaneously engaging the main limiting buckle with the outer wall of the lower corner column. Then, the secondary beam is installed from top to bottom. The main beam is positioned with the lower corner column along its length, which avoids the axial backlash of the main beam causing the clearance notch to shift. This allows the secondary beam to be smoothly and accurately inserted into both the lower rectangular notch and the clearance notch of the main beam for assembly, effectively improving the ease of assembly.

[0031] like Figure 2-4 As shown, a downward-facing main limiting buckle 21 is integrally connected to the lower side of the end of the main beam 2. The end of the main beam 2 extends horizontally through the lower corner post 1, and the main limiting buckle 21 engages with the outer wall of the lower corner post 1. Both side walls of the end of the main beam 2 have vertically extending main overlapping pieces 23 along the length of the main beam 2.

A downward-facing secondary limiting buckle 31 is integrally connected to the lower side of the secondary beam 3. The secondary beam 3 is supported on the lower corner post 1, and the end of the secondary beam 3 extends out of the lower corner post 1, so that the secondary limiting buckle 31 engages with the outer wall of the lower corner post 1. The two side walls at the ends of the sub-beam 3 have vertically extending sub-lapped pieces 32 along the length of the sub-beam 3. Two sets of limiting buckles 31 are integrally connected to the lower edge of the two sets of lapped pieces 32. The main lapped piece 23 and the sub-lapped piece 32 are staggered vertically.

First, one end of the main beam 2 is inserted downward into the lower rectangular notch 11, and the main overlapping piece 23 is inserted into the lower cut 12 so that the main limiting buckle 21 is engaged with the outer wall of the lower corner column 1. At the same time, the positioning protrusion 111 is engaged into the positioning hole 22, so that the main beam 2 is stably positioned along the length and width directions. Then, the clearance notch at the end of the secondary beam 3 is aligned downward with the clearance notch on the upper side of the main beam 2 to form a stable tenon and mortise structure at the ends of the secondary beam 3 and the main beam 2. The secondary limiting buckle 31 is engaged with the outer wall of the lower corner column 1. Finally, the upper corner column 5 is installed downward so that the secondary overlapping piece 32 is inserted into the upper cut 52.
